During BVM ventilation, the patient's chest shows little or no rise. What is the best immediate response?
- A
Squeeze the bag harder and faster to force air into the lungs.
- B
Reposition the head and jaw, reseat the mask, and check for visible obstruction.
- C
Stop checking chest movement and rely on the bag's resistance alone.

Two trained rescuers are available for BVM ventilation. Select all statements that correctly describe the two-rescuer approach.
- A
One rescuer opens the airway and holds a two-handed mask seal while the other squeezes the bag.
- B
The mask is pressed into a seal while the bony jaw is lifted toward it.
- C
The rescuer maintaining the seal should push the soft tissue beneath the chin upward.
- D
Two rescuers can make it easier to maintain a reliable seal while ventilating.

True or false: For an adult in cardiac arrest without an advanced airway, use the CPR compression-to-ventilation protocol—commonly 30 compressions to 2 breaths—instead of the respiratory-arrest ventilation rate.

When monitoring BVM ventilation, select all statements supported by the guidance.
- A
Visible, symmetrical chest rise and fall is a practical immediate check.
- B
When feasible, listening for breath sounds on both sides can help assess air entry.
- C
Waveform capnography can provide breath-by-breath evidence of exhaled carbon dioxide.
- D
An absent breath sound on one side should be treated as proof that ventilation is normal.
- E
Use only one sign to assess ventilation; combining observations is unnecessary.

An adult receiving BVM support has poor circulation, and the pulse-oximetry reading remains low. Which interpretation is most accurate?
- A
It directly measures air movement into and out of the lungs, so other checks are unnecessary.
- B
It always reflects changes in breathing immediately, even when circulation is poor.
- C
It tracks blood oxygen saturation, but readings may lag or be unreliable with poor circulation.
- D
It provides breath-by-breath evidence of exhaled carbon dioxide.

A team has reassessed airway position and mask seal, but effective BVM ventilation still cannot be achieved. What should they do next?
- A
Keep squeezing the bag more forcefully until the chest rises.
- B
Seek advanced airway support without delay.
- C
Continue without reassessment because the initial technique was appropriate.

While ventilating with a bag-mask device, a patient's chest begins to rise after a gentle breath. What should the rescuer do next?
- A
Squeeze the bag rapidly and firmly to ensure a large breath.
- B
Squeeze the bag smoothly until the chest visibly rises, then release fully.
- C
Keep the bag compressed between breaths to maintain airway pressure.
- D
Deliver breaths until the stomach begins to rise.

A clinician is monitoring a patient receiving assisted ventilation. Which statement best describes what pulse oximetry can tell the clinician?
- A
It directly measures the amount of air moving into and out of the lungs.
- B
It provides breath-by-breath evidence of exhaled carbon dioxide.
- C
It tracks blood oxygen saturation, but does not measure ventilation itself.
- D
It reliably shows immediate changes in breathing even when circulation is poor.

One holds the mask with one hand while the other closes the airway during each breath.
- C
One squeezes the bag while the other presses on the soft tissue beneath the chin.

- B
Press the soft tissue beneath the chin to open the airway.
- C
Keep the airway closed and rely on supplemental oxygen.

During bag-mask ventilation, a patient's stomach visibly distends. Which response best addresses this problem?
- A
Increase the force and volume of each breath to overcome the problem.
- B
Reduce volume and pressure, slow delivery, allow full exhalation, and reassess the seal and airway.
- C
Continue at the same rate but hold each breath in longer.
- D
Stop checking the airway and rely only on the pulse oximeter.
